To get us ready for the three-round internet event, the cast has joined forces to make a video explaining how it’s all going to go down.

To sum things up, this is how it’s going to work:

Each team will post three dubsmash videos.

Every dollar donated equals one vote for the team of your choice and one entry into a contest to win lunch with Hayley Atwell, Clark Gregg, Chloe Bennet and James D’Arcy and shoot a dubsmash with them.

Whichever teams raises the most money wins.

The losing team will perform a dubsmash of the winner’s choosing and donate $2,000 to the rival charity.

The first video will premiere on the Dubsmash Wars site on Wednesday, Sept. 2 with new videos premiering every week after. It will end with the last two videos premiering simultaneously on Sept. 30.

In addition to lunch, other prizes will be revealed throughout September. As promised, we’ll keep you up to date on the dubsmash war as it progresses.
